The change in "video: s3c-fb: modify runtime pm functions" (commit35784b) renders the runtime power management for the device completelyineffectual as while it leaves runtime power management notionallyenabled a runtime power reference is held for the entire time the deviceis registered meaning it will never actually do anything.

A further issue is introduced as runtime power management is addedduring the system suspend path which is not something which drivers aresupposed to do and would interact poorly if there were any operationsdone in the runtime power management callbacks.

While this does make things simpler (the main motivation for theoriginal change) it will not only cause us to use more power in theframebuffer controller but will also prevent us entering lower powerdomain and SoC wide states as we can never power down the domaincontaining the device. Since neither of these things is desirablerevert the change.
